I dont know what you guys are talking about, but Federer has the greatest Cross Court forehand of all time. When he whips it from the middle of the court to the left side, its usually the end of the point.

playing like that is what lost him the 2009 USO final to a player with a better cc forehand

federer's signature shots are tweeners and sliced overheads.

Fed has hit so many unique shots, but the one he keeps doing quite often and that I've never seen anyone else hit is the fake dropshot slice winner.

Not consistent enough to be a signature shot though. It's truly unique in his game (as is he smash smash winner and the hot dog) but he can't use it often enough to be called a signature shot. So with that being said, half volleys off any kind of shot his opponent plays it is. I mean a recent example is Nadull in the wind in that IW SF. That was some sick BHs he was playing. Truly genius.

For me, Federer's signature shot is the backhand flick pass. That is extremely idiomatic of Federer. Nalbandian has the rolled backhand that has a lot of spin and creates a short angle. That's probably his signature and certainly one of my favourite shots of any player. I recall Rios was also fond of it, typically used by players who are considered to be prodigious talents.

Champions deserve whatever they win playing within the laws of the game
